1. Introduction
The AccuraUWB FXUWB10 flexible polymer antenna, at 35*24.5*0.2 mm, is a small
form factor, ultra-thin Ultra-Wideband (UWB) antenna with high efficiencies across
the pulsed UWB communications operational bands. It is assembled by a simple
“peel and stick” process, attaching securely to non-metal surfaces via 3M adhesive.
It enables designers to use only one antenna that covers all available UWB
commercial bands, namely bands 1 through 15 simultaneously.
The AccuraUWB antenna is a durable flexible polymer antenna that has average
peak gain of 5dBi, an efficiency of more than 75% across the bands and is designed
to be mounted directly onto a plastic cover. It is an ideal choice for any device
maker that needs to keep manufacturing costs down over the lifetime of a product.
It is ground plane independent and delivered with a cable and connector for easy
connecting to the wireless module or customer PCB. Cables and Connectors are
customizable, however maximum microcoax cable length is 100 mm. Like all such
antennas, care should be taken to mount the antenna at least 10mm from metal
components or surfaces, and ideally 20mm for best radiation efficiency.
Like all such antennas, care should be taken to mount the antenna at least 10mm
from metal components or surfaces, and ideally 20mm for best radiation efficiency.
Ultra-wideband (also known as UWB) is a low power digital wireless technology for
transmitting large amounts of digital data over a wide spectrum of frequency bands
typically spanning more than 500MHz with very low power for short distances.
While the cable type and length are customizable, as is the connector, do note that
a custom designed antenna may be needed in those circumstances. Also tuning of
the antenna may be needed in specific customer device environments. Taoglas
offers this testing and tuning service subject to NRE and MOQ. Contact your regional
Taoglas office for support.
The low power requirements of UWB mean increased battery life of sensors and tags
leading to reduction in overall operational costs. Taoglas has developed various

SPE-17-8-052/A/AZ Page 3 of 18
innovative and new-to-market flexible embedded UWB antennas designed for
seamless integration on plastics and using highly flexible micro-coaxial cable
mounting while achieving high performance where space is limited. Taoglas UWB
antennas have been designed for use with the recently launched Decawave ScenSor
DW1000 module and are also compatible with any other UWB sensor modules on
the market.
1.1. Applications of Pulsed UWB antenna Technology
Radar- These short-pulsed antennas provide very fine range resolution and
precision distance and positioning measurement capabilities. UWB signals
enable inexpensive high definition radar antennas which find use in
automotive sensors, smart airbags, and precision surveying applications
amongst many others.
Home Network Connectivity-Smart home and entertainment systems can
take advantage of high data rates for streaming high quality audio and video
contents in real time for consumer electronics and computing within a home
environment.
Position location & Tracking- UWB antennas also find use in Position
Location and Tracking applications such as locating patients in case of critical
condition, hikers injured in remote areas, tracking cars, and managing a
variety of goods in a big shopping mall. UWB offers better noise immunity
and better accuracy to within a few cm compared to current localization
technologies such as Assisted GPS for Indoors, Wi-Fi and cellular which are at
best able to offer meter level precision. Tethered Indoor positioning UWB
systems that measure the angles of arrival of ultra-wideband (UWB) radio
signals perform triangulation by using multiple sensors to communicate with
a tag device.

3.6. Group Delay (YZ Plane)
The Total System Group Delay (in seconds) is the total time delay or transmit
time of the amplitude envelopes of the various sinusoidal components of UWB
signals through a device or link budget system. Effectively it is the propagation
delay in transmitting antenna (Tx), propagation channel (Ch), and in receiving
antenna (Rx) summed together.
An even more important parameter is the Group Delay Variation from an average
constant group delay. The group delay ripple is used to quantify this deviation.
Ultimately, deviations from a maximally flat or constant group delay represent
distortions in the output signal which is undesirable. A group delay variation of 100-
150ps or less is considered acceptable for UWB system implementation.

3.7. Group Delay Vs Frequency
The group delay was obtained for two FXUWB10 antennas placed at a far-field
distance of 0.5 m. One of the antennas was kept stationary, while the other was
rotated in 45° intervals.
3.8. Group Delay Vs Theta
The values presented in the following graph for Group Delay vs Theta (azimuthal
rotational angle) are obtained as peak-to-peak group delay values. The benchmark
value for peak-to-peak Group delay over Theta is 150 ps, which is satisfied for all
frequencies from 3GHz to 7GHz and 9GHz to 10GHz. The Group Delay is slightly
increased from 7GHz to 8.7GHz, while for the 8.7GHz to 9GHz the antenna is not
recommended for use.

3.9. Fidelity
The impulse fidelity parameter is a measure of correlation between two impulses in
the time domain r(t) and f(t), most commonly the input and the output one of the
antenna system under study. Unlike other antenna parameters, impulse fidelity
combines the antenna characterization in time, space and frequency in one
parameter.
The pulse fidelity is defined in as:

The maximum fidelity, therefore minimum distortion between the two signals, is
obtained for τ such that the integral term is maximized, which is simply the cross-
correlation of the two normalized signals f(t) and r(t).The maximum fidelity, in this
case, is equal to 1 or 100%. The desired impulse fidelity for UWB antennas is over
0.9 or 90% as stipulated in the FCC Part 15 of the Commission’s Rules Regarding
Ultra-Wideband Transmission Systems (FCC 02-48).
Below is an example of the input signal and signal received in one particular
direction from the antenna.

performance.

7. Application Note Cable Routing
Cable routing is tested for this antenna, as seen below, for four possible cable
routing scenarios. S11 shows only slight influence on the resonance in the low band
(3-5 GHz) which will not influence the antenna performance negatively as the values
are always below -10 dB.
